CAR -COUPLING.

SPECIFICATION forming part of Letters Patent No. 229,4;08, dated June29, 1880.

Application filed April 27, 1880.

Toall whom it may concern Be it known that we, EBENEZER HATHA- WAY andTHOMAS H. MYERS, of Hum e, in the county of Edgar and-State of Illinois,have invented a new and Improved Oar-Coupler, of which the following isa specification.

The object of this invention is to provide a self-coupling coupler, bythe use of which the necessity of going between the cars for the purposeof uncoupling will be avoided.

The invention consists, in combination with a draw-head having avertical mouth or linkopening, of two parallel, or nearly parallel, rodsor bars adjusted longitudinally within said draw-head and connected attheir lower ends by a cross-bar, the one longitudinal bar or rod havingan end projecting through the face of the draw-head for the oppositedrawhead to strike against, and below this end, and within thedraw-head, a square shoulder, and having its rear end resting on aspring, while the other bar or rod is pivoted at its lower or rear endon the opposite side of the drawhead, and, extending forward, haspivoted in its front end the coupling-pin, that moves transverselyacross the link-opening, so that when the projecting end of thefirst-mentioned bar is pushed inward the coupling-pin is thereby thrownthrough the coupling-link, and so that when the coupling-pin iswithdrawn from the link the end of the first-mentioned bar againprojects from the face of the draw-head; and it further consists of aspring-actuated lever adjusted on the top of the draw-head and operatingto hold the coupling-pin in the link or to release it therefrom.

Figure 1 is a side elevation of the device coupled. Fig. 2 is afrontelevation of a drawhead with the device attached. Fig. 3 is a plan ofthe device with top plates of drawhea-ds removed to exhibit the interiorparts.

(No model.)

hole a, and on the said bar B, immediately inside of the face of thedraw-head A, a square shoulder, o, is formed. The rear or inner end ofsaid barB passes through an end of acrossbar, 0, and below or rearwardof this bar 0 is encircled by and rests in a spiral spring, D, whichspring D is secured about a stud, c, fixed in the rear end of thedraw-head A. This cross-bar O is rigidly connected with the lower end ofthe bar E, at right angles thereto, or forms part of the same, and attheir point of junction said bars O and E are pivoted by a pin, d,within the said draw-head A, and the bar E extends parallel with the barB forward nearly to the front of the draw-head A, and has pivoted in itsforked end the coupling-pin F, that extends transversely across thedraw-head parallel with the cross-bar 0.

Within the head of the draw-head A, and directly in rear of thelink-opening a, is fixed a box, G, that serves as a stop to prevent thelink H from entering too far into the said draw-head A when coupling,and also to prevent an excessive lateral movement of said link. Twoopposite side openings, 9 g, are formed in said box G, to admit of thepassage of the coupling-pin F.

K is a right-angled lug fastened on the head of the draw-head A, andhaving a forked end extending horizontally over a side of the same, inwhich forked end the vertical lever L is pivoted. The other end of thislug K extends vertically upward and supports a horizontal stud, h, thatis directed toward the lever L and carries the encircling-spring M,which presses against said lever L and operates it. The long arm of thislever L extends upward within reach of the brakeman, and can have across-bar, as indicated at N, attached to it for convenience ofoperating from the sides of the cars, and the short arm of the saidlever L, extending downward, is bent inward at right angles and heldagainst the shoulder o of the bar B.

The coupling-link H is straight on one edge (the upper) and curved orrounding on the opposite edge, the curve enabling the said link to enterthe draw-head more easily, and the straight edge preventing the saidlink H from passage of the end of the actuating-bar B. drooping.

The forward end, b, of said bar B rests in this On the left, in Fig. 3,the link H is shown held in a draw-head, A, in position for coupling. Asthis draw-head approaches the opposite or right-hand draw-head the linkH enters the mouth a of said right-hand drawhead, and the projecting endof the bar B being struck by the approaching draw-head, the said bar Bis forced backward, with the effect of moving the bar E on its pivot d,and there by throwing the coupling-pin F through said link H, andsimultaneously with this movement the spiral spring M operates to forcethe short arm of the lever L between the shoulder c of this bar B andthe end of the containing draw-head, so as to hold the said bar Bretracted, and consequently the connected coupling-pin F in thecoupling'link.

To uncouple, the long arm of the lever L is moved inward, with'theefl'ect of withdrawing the short arm of the said lever L from engagementwith the shoulder c of the bar B, when instantly the spring D operatesto force the end of said bar B forward through the hole a, and at thesame time to withdraw the coupling-pin F from the link H, and thusuncouple the cars.

Having thus described our invention, We claim as new and desire tosecure by Letters Patent- 1. A car-coupler, constructed substantially asherein shown and described, consisting of 30 draw-head A, provided withvertical link-opening a and hole a, spring-actuated bar B, withprojecting end b and shoulder c, cross-bar C, pivoted bar E, providedwith coupling-pin F, gprilng-actuated lever L, and link H, as set 35 ort2. The combination, with draw-head A, having the link-opening a and holea, of the bar B, having an end, b, in hole a, and the shoulder 0, thebar 0, held on bar B by the spring 0 D, the bar E, pivoted to bar 0 atone end and having on the other a vertical pin, F, and the box G, havinghole g, as shown and described.

3. In a car-coupler, the combination, with the spring-actuated bars B OE and coupling- 5 pin F, of the spring-actuated lever L, substantiallyas herein shown and described.

4. In a car-coupler, the combination, with the spring-actuated bar B,provided with a shoulder, c, and projecting end b, of the 50spring-actuated lever L, substantially as herein shown and described.
